Objective To explore perioperative management and postoperative effectiveness of hemophilia induced lesions of the foot and ankle. Methods Between June 1998 and February 2012, 10 cases (12 feet) of hemophilia induced lesions of the foot and ankle were treated with surgery, including 9 cases (11 feet) of hemophilia A and 1 case (1 foot) of hemophilia B. Single foot was involved in 8 cases and both feet in 2 cases, including 3 left feet and 9 right feet. All were males, aged from 13-41 years (mean, 22.6 years). Disease duration was 5-84 months (mean, 32.2 months). Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score was 43.2 ± 21.1. Short Form 36 Health Survey Scale (SF-36) score was 45.4 ± 20.0. All patients were given clotting factors (2 000-3 500 U) for pre-experiment and clotting factors substitution therapy was performed perioperatively. Four cases (4 feet) underwent arthrodesis, and 7 cases (8 feet) underwent Achilles tendon lengthening/tendon transposition (1 patient underwent tendon lengthening on the left foot and arthrodesis on the right foot). Results The operation time was 65-265 minutes (mean, 141.1 minutes); 1 case had 400 mL blood loss and 200 mL autogenous blood transfusion, the other cases had less than 50 mL blood loss and no blood transfusion. Wounds healed by first intention in all patients, no postoperative infection, deep vein thrombosis, or other complications occurred. All cases were followed up 6 months to 14 years and 3 months (median, 22 months). The X-ray films at last follow-up showed the patients undergoing arthrodesis obtained complete joint fusion. AOFAS scores at postoperative 6 months and last follow-up were 78.8 ± 14.7 and 75.8 ± 14.5, respectively; SF-36 scores were 76.6 ± 13.1 and 75.5 ± 13.2, respectively; and significant differences were found when compared with preoperative scores (P lt; 0.05), but no significant difference between postoperative 6 months and last follow-up (P gt; 0.05). Conclusion For patients with hemophilia induced lesions of the foot and ankle, surgical treatment could relieve foot and ankle pain and improve the function. Clotting factors pre-experiment at preoperation and substitution therapy at perioperation can reduce the risk of severe postoperative hemorrhage.
Objective To give a review and commentary on the treatment of acute foot and ankle injuries. Methods Based on the treatment experience and recent l iterature, a commentary on acute foot and ankle injuries were given, included the basic and cl inical research results, evaluation before operation, and treatment methods of the soft tissue and bone injuries. Results The treatment of acute foot and ankle injuries is still a hot point in orthopaedic surgery. Operative and non-operative treatment of fresh Achilles tendon rupture can achieve satisfactory results, and early weight-bearing do not increase the re-rupture rate. The time delay between first debridement and injury within 24 hours does not increase the infection rate. For the treatment of severe ankle fractures, attentions should be paid to the cartilage injury, and anatomic reduction, good real ignment, and the congruity recovery are very important. The treatment determination of calcaneal fractures depends on the fully understanding injury mechanisms, classifications, and treatment method. Talus fractures should try to be treated by experienced surgeons. Operation and fixation methods of Lisfranc injury depends on different injury types. Conclusion Acute foot and ankle injuries are common in cl inical, to achieve a satisfactory result in evaluation and treatment, it is important to have a fully evaluation of the injury type, and choose the best operation time and suitable treatment methods, as well as to fully understand the biomechanical characteristics of different regions.
Objective To investigate the operative techniques and cl inical results of sural neurocutaneous vascular flap pedicled on the relatively higher and main perforating branch of peroneal artery in repairing small and medium-sized soft tissue defects in ankle. Methods From July 2004 to February 2007, 14 patients (9 males and 5 females, aged 19-53 years) withsmall and medium-sized soft tissue defects in ankle were treated, including 4 cases of skin necrosis caused by surgery for achilles tendon rupture, 3 soft tissue defects due to car accident, 2 crush injury due to fall ing heavy objects, 2 chronical infectious ulcer, 2 skin necrosis cuased by surgery for calcaneus fracture and 1 melanoma resection in heel. Ranging from 4 cm × 2 cm to 9 cm × 5 cm and combing with exposure of either tendon or bone, the defects were in ankle areas (12 cases) and weight-bearing heel (2 cases). The time from injury to hospital ization was 12 days to 13 months, except 3 cases of emergency hospital ization. After thorough debridement, the sural neurocutaneous vascular flaps (13 cm × 5 cm - 36 cm × 6 cm ) pedicled on the perforating branch of peroneal artery was harvested to repair the defects. The donor sites were sutured directly. Results Postoperatively all the flaps survived, and all the donor sites and wounds healed by first intention. Over a 7-23 month follow-up period, the texture, appearance and color of the flaps in all cases were good, with two-point discrimination of 7-12 mm.The function of ankle obtained satisfactory recovery with normal in-shoe gait. Conclusion With a rel iable blood supply, simple operative procedure, sound repair of wound and satisfactory recovery of l imb function, the sural neurocutaneous vascular flap pedicled on the relatively higher and main perforating branch of peroneal artery is appl icable for the repair of small and medium-sized defects in the ankle and weight-bearing area of heel, especially for patients who have no satisfactory perforating branch in lower position.
